CULTIVA'TOR.

SPECIFICATION forming part of Letters Patent No. 735,886, dated A ust 11, lees. Application filed February 13, 1903. $eria1 No. 143,260. (No modelil T0 at whom it may concern:

Be it known that I, SAMUEL P. KIMBALL, a citizen of the United States, residing at Salem, in the county of Marion and State of Oregon, have invented a new and useful Cultivator, of which the following is a specification.

This invention relates to cultivators, more particularly to the class employed in orchards and similar contracted and tortuous localities, and has for its object to produce a-simplyconstructed and easily-operated implement of this character which may be very cheaply manufactured and operated with a relatively small expenditure of power and which may be employed in the vicinity of trees and other fragile vegetation without danger of injury thereto.

The invention consists in certain novel features of construction, as hereinafter shown and described, and specified in the claims.

In the drawings illustrative of the invention, in which corresponding parts are denoted by like designating characters, Figure 1 is a bottom plan view of the device complete. Fig. 2 is alongitudinal sectional elevation.

The improved device consists of a platform 10, having shoes or runners 11 12, extending beyond the rear edge of the platform, as shown. Supported movably upon the extensions of the runners is a cultivator-frame consisting of a base-plate 13, from which the cultivator-teeth 14 extend at reversely-inclined angles, as shown, the teeth being preferably formed of spring-plates twisted a part of a revolution and bent in opposite directions at both vertical and lateral angles to the baseplate. By this arrangement the teeth are equally divided upon each side of the center, so that the draft will be equal when the resistance is equal.

The cultivator-blades will bespaced apart and so disposed that theiroperative portions will overlap, as indicated in Fig. 1, so that no by a longitudinal bar 17, and between this rear bar and the plate 13 are other bars 18 19 and providing supporting means for the drivers stand 20, as shown. The drivers stand and fender-bars and supporting-frame thus stand at an angle relative to the teeth 14 and platform 10, as indicated in Fig. 2.

Connected to the forward edge of the baseplate 13 are draft-chains 21 22, extending forwardly and terminating in a ring 23, which unites the two chains. The chains pass be neath the platform 10 and are connected there to, as indicated at 24 25, the chains thus serv= ing the double purpose of draft means to the platform and cultivator-frame and likewise as a flexible coupling between the platform and cultivator-frame. The draft-team will be connected to the chains 21 22 in any suitable manner, as by the usual doubletrees 28 and swingletrees 29 when two horses are employed or by a swingletree only when one horse is employed.

Extending upwardly from the base-plate 13 is an operating lever-arm 26, convenient to the hand of the operator upon the stand 20 and suitably braced from the plate to secure the necessary rigidity.

\Vhen thus constructed, the operation is as follows: The driver takes his place centrally upon the stand 20 to add his weight to the device, and by moving from side to side he can easily regulate the draft and cause the device to be deflected to either side or increase or decrease the depth of the out of the teeth by changing his position nearer to or farther from the platform 10, as will be obvious- If the cultivator-teeth become clogged or if for any other reason it is desirable to elevate the teeth free from the ground, the driver steps to the platform 10 and draws the lever-arm 26 forward, which will tilt the cultivator-frame and raise the teeth free from the ground and free them from obstructions.

The device is thus very simple and easy to operate, speedy, and effective in action, leaving the ground smooth and uniformly pulverized and free from weeds and other obj ectionable growth.

The device can be manufactured in any desired size and is capable of employment wherever implements of this character are usually required, but, as before stated, is more particularly applicable for use in orchards and similar contracted and tortuous localities, wherein the fender-bars perform an important function in preventing injury to trees or other vegetation and likewise protecting the cultivator-teeth from injury from objects which they might otherwise strike.

Having thus described the invention, what I claim is 1. A cultivator consisting of a platform adapted to be drawn over the ground, a frame having cultivatorteeth and movably connected to said platform, and fenders extending from said frame beyond the cultivatorteeth, substantially as described.

2. A cultivator comprising a platform having runners and adapted to be drawn over the ground, a frame having cultivator-teeth, a platform supported upon said frame above said cultivator-teeth, a link connection be tween the front platform and the rear frame, and a lever-handle extending upwardly fro the latter.

3. In an implement of the class described, the combination of a front platform mounted upon runners, a frame resting upon the rear ends of said runners and having cultivatorteeth engaging the ground, a link connection between the front platform and the frame, and a platform supported by the latter above the teeth.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

SAMUEL P. KIMBALL.
